It has been reported that some patients have been misdiagnosed with Painless Thyroiditis, when in fact the correct diagnosis in their specific case was Overactive Thyroid.
A simple blood test to measure thyroid hormone levels can easily diagnose hyperthyroidism. Graves disease can also be checked by checking the level of thyroid stimulating antibodies. The treatment options vary and include consumption of radioactive iodine, medications to control the levels of hormones produced by the thyroid, as well as surgery to remove most of the thyroid glands although this is performed in rare conditions.
